Is it permissible to rebel against the ruler?

There are people who think that because some
of the rulers commit acts of kufr and sin, we
are obliged to rebel against them and attempt
to change things even if that results in harming
the Muslims in that country, at a time when
there are many problems in the Muslim world.
What is your opinion?

Praise be to Allaah.
The basic comprehensive principle of sharee’ah
is that it is not permitted to remove an evil by
means of a greater evil; evil must be warded
off by that which will remove it or reduce it.
Warding off evil by means of a greater evil is
not permitted according to the scholarly
consensus (ijmaa’) of the Muslims. If this
group which wants to get rid of this ruler who
is openly committing kufr is able to do so, and
can bring in a good and righteous leader
without that leading to greater trouble for the
Muslims or a greater evil than the evil of this
ruler, then that is OK. But if rebellion would
result in greater trouble and lead to chaos,
oppression and the assassination of people
who do not deserve to be assassinated, and
other forms of major evil, then that is not
permitted. Rather it is essential to be patient
and to hear and obey in matters of good, and
to offer sincere advice to the authorities, and
to pray that they may be guided to good, and
to strive to reduce evil and increase good. This
is the correct way which should be followed,
because that is in the general interests of the
Muslims, and because it will reduce evil and
increase good, and because this will keep the
peace and protect the Muslims from a greater
evil.
